The applicant has noticed that the cover of the conventional display device has a problem of structural damage such as cracks or deformation, and then has conducted research and analysis on each structure of the display device. The applicant has found that in the non-display region of existing display devices, the cover plate is attached to the center frame assembly by an adhesive. Because the part that the apron is located the non-display area is whole to bond on the center subassembly, consequently when there is unevenness in the part that corresponds the non-display area on the apron, can bear compressive stress towards center subassembly sunk part, and can bear tensile stress towards the bellying of keeping away from center subassembly direction bulge to there can be the inhomogeneous condition of atress in unevenness's region, and then lead to some regions of apron to produce the problem of crack or deformation because of stress concentration. After further research and analysis, the applicant finds that the edge areas of the cover plate, which are positioned in the non-display area, are bonded with the middle frame assembly, so that the bonding area of the edge areas of the cover plate is large, and when the cover plate is stressed, the internal stress is not easy to buffer or release, and the problem of cracks or deformation is caused.

Based on the above problems discovered by the applicant, the applicant has improved the structure of the display device, and further described the embodiments of the present invention.

For a better understanding of the present invention, embodiments of the present invention are described below with reference to fig. 1 to 12.

Fig. 1 schematically shows a front structure of a display device 1 of an embodiment. Referring to fig. 1, a display device 1 of an embodiment of the present invention has a display area 1a and a non-display area 1b located on the peripheral side of the display area 1 a. The display area 1a is used for displaying visual images and can also be used as a touch control area for a user.

Fig. 2 schematically shows an exploded structure of the display device 1 of the embodiment shown in fig. 1. The display device 1 according to the embodiment of the present invention includes a cover 10, a display panel 20, a middle frame assembly 30, and a backlight assembly 50. A receiving space is formed between the cover 10 and the bezel assembly 30. The receiving space is for receiving the display panel 20. The display panel 20 corresponds to the display area 1a, and is used for displaying a visual image or performing touch control. The backlight assembly 50 is used to provide a light source for the display panel 20. The display panel 20 of the present embodiment may include a touch control layer, a color film substrate, a liquid crystal layer, and an array substrate. In some other embodiments, the display device 1 may not be provided with the backlight assembly 50, and the display device 1 may be in the form of a self-light emitting unit, so that the display panel 20 displays a visualized image. Here, the display panel 20 is not limited to the manner of displaying an image and the selection of a light source.

Fig. 3 schematically shows a cross-sectional structure of the display device 1 of the embodiment shown in fig. 1 along the a-a direction. Referring to fig. 3, the cover 10, the display panel 20 (not shown), the middle frame assembly 30 (not shown), and the backlight assembly 50 are stacked in the thickness direction X. The backlight assembly 50 is located at one side of the cover 10. The cover 10 is connected to the middle frame assembly 30, and the backlight assembly 50 is connected to the middle frame assembly 30. The middle frame assembly 30 may provide support for the backlight assembly 50 and the cover 10.

Fig. 4 schematically shows an enlarged view at B in fig. 3. Referring to fig. 4, the cover 10 includes a cover plate 11 and an adaptor 12. The cover plate 11 has a side surface 11a facing the middle frame assembly 30 and corresponding to the non-display area 1 b. The adaptor 12 is disposed on the side surface 11 a. The display panel 20 is located on the same side of the cover plate 11 as the adaptor 12. The middle frame assembly 30 is connected to the cover plate 11 through the adaptor 12. In one example, the cover plate 11 is a transparent structure, and the material of the cover plate 11 may be glass or plastic.

Fig. 5 schematically shows the structure of the cover 10 according to an embodiment. Referring to fig. 5, two or more adapters 12 are provided at intervals along the peripheral side of the display area 1 a. In this embodiment, the cover plate 11 has a frame 111 disposed corresponding to the non-display area 1 b. In one example, the cover plate 11 includes four bezels 111. Two opposing frames 111 form a set of frames 111. The two sets of frames 111 are provided with the adapters 12. It will be appreciated that in other embodiments, adapters 12 may be provided on only one set of rims 111.

In the display device 1 according to the embodiment of the present invention, the cover plate 11 is provided with more than two adapters 12, and the middle frame assembly 30 is connected to the cover 10 through the adapters 12. Because each adapter 12 is the interval setting, consequently, the apron 11 is connected the back with center subassembly 30, the region that lies in between two adjacent adapters 12 on the apron 11 is difficult for receiving the restraint of center subassembly 30, thereby even when the region that lies in between two adjacent adapters 12 on the apron 11 appears the inhomogeneous condition of stress that receives, the internal stress of apron 11 also can obtain buffering or release, be favorable to reducing and lead to the unable buffering of internal stress of apron 11 or release to make apron 11 appear the possibility of crackle or deformation because of laminating with center subassembly 30 is complete, also make adapter 12 difficult for taking place to separate and drop with center subassembly 30 because of the long-term effect of the internal stress of apron 11, and then be favorable to prolonging display device 1's life, be favorable to improving the structural integrity when apron 11 uses for a long time, reduce maintenance loss cost. In addition, the adaptor 12 can occupy a smaller area on the cover plate 11, so that the area of the part of the cover plate 11 corresponding to the non-display area 1b, which is printed with silk ink, can be reduced, the area of the part of the cover plate 11 corresponding to the non-display area 1b can be reduced, and the display device 1 can achieve the display effect of a narrow frame or a full screen. Moreover, because the center frame assembly 30 and the adapter 12 are convenient to disassemble and assemble, the center frame assembly 30 and the adapter 12 can be easily separated in the later maintenance or repair process, the maintenance difficulty is reduced, and the maintenance friendliness is improved.

In one embodiment, referring to fig. 4, the adapter 12 and the cover plate 11 are adhesively attached. By adopting the bonding mode, the structural design complexity of the cover plate 11 and the adapter 12 can be reduced, the processing procedures of the cover plate 11 and the adapter 12 can be simplified, and the processing difficulty of the cover plate 11 and the adapter 12 can be reduced. In addition, the bonding mode is adopted, so that the connecting operation difficulty can be reduced, and the possibility that the transfer piece 12 scratches the silk-screen printing ink on the cover plate 11 in the connecting process is reduced. In one example, the cover plate 11 is coated with an adhesive or pasted with an adhesive tape, and then the adaptor 12 is attached to the adhesive or the adhesive tape, thereby completing the connection and fixation of the adaptor 12 and the cover plate 11. In one example, the adapter 12 may be a rectangular structure. The adaptor 12 may have a length of 14mm to 30mm and a width of 6mm to 15 mm. The thickness of the bonding layer formed by the bonding glue or the bonding adhesive tape is 0.15mm to 0.35 mm.

In one embodiment, the material of the adapter 12 may be aluminum or an aluminum alloy, thereby providing the adapter 12 with good strength while also maintaining light weight and good workability of the adapter 12. In other embodiments, the material of the adaptor 12 may also be plastic.

In one embodiment, as shown in FIG. 4, the display device 1 further comprises a flexible gasket 60. A flexible gasket 60 is provided between the middle frame assembly 30 and a portion of the cover plate 11 corresponding to the non-display region 1 b. The flexible seal 60 has compressibility and good resiliency. The flexible sealing gasket 60 can isolate the middle frame assembly 30 from the cover plate 11, so that the possibility that the middle frame assembly 30 scratches the screen printing ink of the cover plate 11 when the middle frame assembly 30 and the cover body 10 are assembled is reduced, and the phenomenon that external dust, water vapor and other substances enter the display device 1 from the space between the middle frame assembly 30 and the cover plate 11 is also reduced. In one example, the flexible seal 60 may be a cushion foam.

In one embodiment, referring to FIG. 4, the center frame assembly 30 and the cover plate 11 have a receiving gap 100 therebetween. In the embodiment where the adaptor member 12 and the cover plate 11 are adhesively bonded together using adhesive, the receiving gap 100 can be used to receive adhesive that may overflow between the adaptor member 12 and the cover plate 11, thereby reducing the possibility that the adhesive will contact the center frame assembly 30 and bond to the center frame assembly 30, which may make the center frame assembly 30 less likely to be disassembled. In one example, the receiving gap 100 is an annular space surrounding the adapter 12.

In one embodiment, as shown in FIG. 4, the display device 1 further includes a fastener 40. The fastener 40 locks the adaptor 12 and the center frame assembly 30. The fastening member 40 can be used to fasten the adaptor 12 and the middle frame assembly 30 after the cover 10 and the middle frame assembly 30 are assembled, so as to improve the connection stability and reliability of the cover 10 and the middle frame assembly 30. In one example, the fastener 40 is fastened to the adaptor 12 by a threaded connection, so that the fastener 40 can be easily detached when the middle frame assembly 30 and the cover 10 need to be separated or fastened. In one example, the middle frame assembly 30 has a recess extending in the thickness direction X and a mounting hole communicating with the recess. At least part of the adaptor 12 is located within the recess. The adaptor 12 has a threaded hole provided corresponding to the mounting hole. The fastener 40 may be a stepped screw in which the smaller diameter section is a threaded section. The fastener 40 passes through the mounting hole and threadably engages the threaded hole of the adapter 12. In the thickness direction X, an adjustment gap is reserved between the nut of the fastening member 40 and the middle frame assembly 30, so that the cover body 10 has a movement amount along the thickness direction X, and the possibility that the cover plate 11 falls off due to the fact that the bonding layer between the adapter 12 and the cover plate 11 and the silk-screen ink on the cover plate 11 are in a tensile force bearing state for a long time after the fastening member 40 is locked is reduced, and the silk-screen ink falls off, the bonding layer is separated from the cover plate 11 or the bonding layer is separated from the adapter 12. In one example, the material of the adapter 12 may be aluminum or an aluminum alloy. Alternatively, the adaptor 12 comprises a plastic body and a nut embedded within the plastic body. The fastener 40 is threadedly coupled to the nut. In another example, the fastener 40 and the adaptor 12 may be locked by a snap-fit connection. The fastener 40 has a snap-fit configuration and the adapter 12 has a catch. The fastener 40 can be fastened in the fastening groove of the adapter 12, so that the fastener 40 and the adapter 12 are connected and fixed, and the fastener 40 locks the adapter 12 and the center frame assembly 30.

Fig. 6 schematically shows a front structure of a display device 1 according to another embodiment of the present invention. Fig. 7 schematically shows a sectional structure in the C-C direction in fig. 6. Fig. 8 schematically shows an enlarged view at D in fig. 7.

In an embodiment, referring to fig. 8, the same structure as that in the embodiment shown in fig. 1 is not repeated, and please refer to the above embodiment. The differences are mainly described in this embodiment. The adaptor 12 of the present embodiment includes a connecting portion 121 and a cantilever portion 122. The connection portion 121 and the cantilever portion 122 are connected to each other. The adaptor 12 is connected to the side surface 11a of the cover plate 11 by the connection portion 121. The fastener 40 locks the cantilever portion 122 and the middle frame assembly 30. In one example, the connecting portion 121 and the cantilever portion 122 are an integrally molded structure. The adaptor 12 can be more flexibly connected with different positions of the middle frame assembly 30 through the cantilever part 122, so that the connection position selection flexibility and the connection position structural design flexibility of the middle frame assembly 30 and the adaptor 12 are improved, the internal space utilization rate of the display device 1 is favorably optimized, and the overall structural compactness is ensured.

As shown in fig. 8, the cantilever 122 is disposed at the connecting portion 121 near the edge of the display panel 20. The cantilever portion 122 extends from the connection portion 121 toward the display panel 20. The cantilever portion 122 and the cover plate 11 form an accommodating gap 100 therebetween. In the embodiment where the adaptor member 12 and the cover plate 11 are adhesively bonded using the adhesive, the receiving gap 100 can be used to receive the adhesive that overflows between the adaptor member 12 and the cover plate 11, thereby reducing the possibility that the adhesive will stick to the middle frame assembly 30 or the fastener 40 by contacting the adhesive with the middle frame assembly 30 or the fastener 40, thereby making the middle frame assembly 30 or the fastener 40 difficult to detach. In addition, the accommodation gap 100 can be made to escape from the display panel 20, so that the internal structure of the display device 1 is improved, and the adaptor 12 is less likely to interfere with the display panel 20. In one example, a gap is formed between an edge region of the cantilever portion 122 away from the connecting portion 121 and the middle frame assembly 30, so as to avoid position interference between the cantilever portion 122 of the interposer 12 and the middle frame assembly 30. In one example, the connecting portion 121 has a rectangular structure, and the cantilever portion 122 has a rectangular structure.

In one embodiment, referring to fig. 8, a gap 200 is formed between the adaptor 12 and the middle frame assembly 30 in the thickness direction X, so that the cover 10 has a movement amount in the thickness direction X, and the possibility that the cover 11 falls off due to peeling of the silk-screen ink, separation of the adhesive layer from the cover 11, or separation of the adhesive layer from the adaptor 12 caused by the fact that the adhesive layer between the adaptor 12 and the cover 11 and the silk-screen ink on the cover 11 are under tension for a long time after the fastening member 40 is locked is reduced.

In one embodiment, referring to fig. 8, the adapter 12 has a stop recess 300 extending in the thickness direction X. The stop recess 300 has an opening on the surface of the adapter 12 facing away from the cover plate 11. The middle frame assembly 30 has a limit protrusion 400 extending and protruding in the thickness direction X. The limit convex part 400 is matched with the limit groove 300 in an inserting way. When the cover 10 and the middle frame assembly 30 are assembled, the position limiting protrusion 400 is inserted into the position limiting groove 300 to complete the positioning and limiting of the middle frame assembly 30, so as to ensure that the middle frame assembly 30 is quickly and accurately positioned at a predetermined position, and then the fastener 40 is used to lock the middle frame assembly 30 and the cantilever portion 122. In one example, the limiting groove 300 is correspondingly disposed on the connecting portion 121 of the adaptor 12. In another example, the adaptor 12 has a limiting protrusion 400, and the middle frame assembly 30 has a limiting groove 300, and the positioning and limiting of the middle frame assembly 30 can also be realized by the limiting protrusion 400 and the limiting groove 300.

In one embodiment, referring to fig. 8, the edge portion of the backlight assembly 50 is snapped to the middle frame assembly 30. The edge of the backlight assembly 50 has a through hole, and the middle frame assembly 30 is also provided with a mounting hole communicating with the through hole. The cantilever 122 has a threaded hole corresponding to the through hole of the middle frame assembly 30. The rod part of the fastener 40 passes through the through hole and the mounting hole and then is in threaded connection with the threaded hole. The cap end of the fastener 40 is overlapped on the edge portion of the backlight assembly 50. The fastener 40 locks the backlight assembly 50, the middle frame assembly 30 and the cantilever portion 122.

Fig. 9 schematically shows a front structure of a display device 1 according to another embodiment of the present invention. Fig. 10 schematically shows an exploded structure of the display device 1 of the embodiment shown in fig. 9. Fig. 11 schematically shows a sectional structure in the direction E-E in fig. 9. Fig. 12 schematically shows an enlarged view at F in fig. 11.

In one embodiment, referring to fig. 9 and 10, the same structure as that of the embodiment shown in fig. 8 in this embodiment is not repeated. The differences are mainly described in this embodiment. The display device 1 of the present embodiment further includes two frame members 70 disposed opposite to each other. Two outer frame members 70 are provided independently of the middle frame member 30 and cooperate with the middle frame member 30.

Referring to fig. 11 and 12, the adaptor 12 of the present embodiment includes a connecting portion 121 and a cantilever portion 122. The cantilever 122 is disposed at an edge of the connection portion 121 away from the display panel 20. The cantilever portion 122 is folded toward the middle frame assembly 30 with respect to the connecting portion 121 and is located outside the middle frame assembly 30. The outer side of the middle frame assembly 30 refers to a side of the middle frame assembly 30 away from the central region of the display device 1. Cantilever portion 122 may define a stop for center frame assembly 30 at the outer side of center frame assembly 30. The adaptor 12 of this embodiment may be disposed on the cover plate 11 near its edge. The surface of the cantilever portion 122 remote from the center frame assembly 30 may be flush with the narrow surface of the cover plate 11. The narrow surface of the cover plate 11 is adjacent to the side surface 11 a. In this way, the adaptor 12 occupies an area on the cover plate 11 closer to the edge, so that the width of the screen printing ink can be further reduced to increase the area of the display area 1 a. In one example, referring to fig. 12, the cross-section of the adaptor 12 may be L-shaped. The outer frame assembly 70 is located outside the cantilever portion 122, and the flexible sealing gasket 60 is disposed between the outer frame assembly 70 and the cover plate 11, which is beneficial to reducing the entry of external dust or moisture and other substances into the display device 1 from between the outer frame assembly 70 and the cover plate 11. In one example, the external frame member 70 overlaps the narrow surface of the cover plate 11. The flexible gasket 60 is located between the narrow surface of the cover plate 11 and the external frame member 70.

In one embodiment, with continued reference to FIG. 12, the middle frame assembly 30 has a first extension 31 located inboard of the cantilever portion 122. The backlight assembly 50 has a second extension 51 positioned inside the first extension 31. At least a portion of the first extension 31 is located between the cantilever portion 122 and the second extension 51. The fastener 40 locks the cantilever portion 122, the first extension 31 and the second extension 51. In one example, the cantilever portion 122 and the first extension 31 have through holes, and the second extension 51 is provided with screw holes corresponding to the through holes. The shaft of the fastener 40 passes through the through holes of the cantilever portion 122 and the first extension 31 and then is screwed into the threaded hole. In another example, through holes are also formed in the casing component 70, and the fasteners 40 pass through the through holes of the casing component 70, the cantilever portion 122 and the first extension portion 31 and then are screwed with the threaded holes of the second extension portion 51, so that the fasteners 40 lock the casing component 70, the cantilever portion 122, the first extension portion 31 and the second extension portion 51. In one example, the through holes on the cantilever portion 122 are kidney-shaped holes, so that the position error can be compensated, the alignment difficulty and the position accuracy requirement of the through holes on the cantilever portion 122 and the through holes on the middle frame assembly 30 are reduced, and the fastener 40 can smoothly pass through the through holes on the cantilever portion 122. In one example, the cross-section of the middle frame assembly 30 may be L-shaped. The buffering foam is disposed between the middle frame assembly 30 and the display panel 20, which is beneficial to preventing dust or moisture from entering between the display panel 20 and the backlight assembly 50.

In the display device 1 according to the embodiment of the present invention, the cover plate 11 is provided with two or more adapters 12, so that the middle frame assembly 30 can be connected to the cover 10 through the adapters 12. Two or more adapters 12 are disposed on the edge region of the cover plate 11 beyond the display panel 20 and are spaced apart along the circumference of the display panel 20. The cover plate 11 and the middle frame assembly 30 are fixedly connected through more than two adapters 12, so that the connecting area of the part, corresponding to the non-display area 1b, of the cover plate 11 and the middle frame assembly 30 is reduced, and the constraint effect of the part, corresponding to the non-display area 1b, of the cover plate 11 on the middle frame assembly 30 is reduced. Therefore, on one hand, when the part of the cover plate 11 corresponding to the non-display area 1b is stressed unevenly, the part of the cover plate 11 between the two adapters 12 is not restrained, so that the internal stress of the part of the cover plate 11 corresponding to the non-display area 1b can be buffered or released through the unrestrained part, and the problem that the cover plate 11 is cracked or deformed is solved; on the other hand, when the portion of the cover plate 11 located between the two adapters 12 has unevenness, the concave portion and the convex portion are not constrained, so that the situation of excessive concentration of internal stress is not easy to occur, and the problem of cracking or deformation of the cover plate 11 is reduced.

The embodiment of the present invention further provides a manufacturing method of the display device 1, which includes:

attaching the display panel 20 to the cover plate 11;

more than two adapters 12 are arranged on the cover plate 11 at intervals beyond the edge area of the display panel 20 along the circumferential direction of the display panel 20, and the adapters 12 and the display panel 20 are positioned on the same side of the cover plate 11;

the center frame assembly 30 is connected to the adapter 12.

In one embodiment, in the step of disposing more than two adapters 12 on the cover plate 11 at intervals along the circumferential direction of the display panel 20 beyond the edge area of the display panel 20, and the adapters 12 and the display panel 20 are located on the same side of the cover plate 11, the adapters 12 are adhered to the edge area.
